Pheasants, although not indigenous, are not rare in the UK, given wealthy people like to shoot them. Normally what happens is the chicks are reared in pens, which themselves are located within small woodlands. Once the birds get to a reasonable size they are released then fed daily by the gamekeeper, who also controls any raptors, until finally, hordes of humans march through the woodland, waving flags and shouting, the birds flying away straight over a line of strategically placed shooters. Such is the "sport" of pheasant shooting.
Some species, such as the Scottish wildcat, the pine marten, and several birds of prey are rare, indeed close to extinction due to gamekeepering, admittedly not just recently. Note though that when the wars were on, many species of raptor, or vermin as they are often known, drastically increased in numbers, because no-one was at home to manage the sporting estates
The Royals like their "field sports".
